Description
Technical field
This utility model, about a kind of pressue device, aims to provide external counterpulsation apparatus, a kind ofly can adjust the pressure keeping after Air sac cover inflation according to demand, and can produce the pressue device of incremental pressurization or relaxation effect.
Background technology
Heart Advances in Medicine is always very fast, particularly the treatment aspect coronary disease disease, heart failure.Except various drug developments, more have in the synchronous pacemaker for the treatment of, heart of cardiac catheter and intravascular stent and body the development such as electric shock device, surgical operation also has rapid progress, even so, still have many patients finish intravascular stent or surgery detour operation after, still have phenomenon uncomfortable in chest or that breathe heavily.
Known can device or heavier-duty external counterpulsation (EECP) device by permeation body extracorporeal counterpulsation (ECP), mechanical assistance endless form with Noninvasive, make Air sac cover coordinate heart beating to do lower limb extruding, by mechanism, improve aortic diastolic pressure, lower aortic systolic pressure, heart coronary flow is increased, and then improve myocardial metabolism and function, even patient, after accepting long-time treatment, can increase the angiogenesis of heart, further improves myocardial function.
In recent years existingly multinomially studies confirm that external counterpulsation apparatus ECP/EECP has increase coronary flow, improve blood flow shearing stress, improve vascular endothelial cell structure and function, prevent thrombosis and promote the advantages such as blood vessel collateral circulation formation.More have research to point out, patient reaches 70 ~ 80% to the response rate cocoa of this treatment clinically, and effect may sustainablely reach the of a specified duration of 2-5.Therefore, medical circles think that external counterpulsation apparatus ECP/EECP is concerning angina pectoris and heart failure patient at present, are that a kind of effective and safe alternative therapy is selected.
More clearly say it, typical case's external counterpulsation apparatus as shown in Figure 1, comprise a plurality of interconnective Air sac covers 11 for entangling patient's extremity, in some ECP systems, can there is extra Air sac cover for entangling patient's femur district and/or buttocks portion, then from the long-range Air sac cover 11 of extremity, connect a pneumatic supply 20, an and group controller 30, make to see through the mode of being pressurizeed in proper order towards the Air sac cover 12 of near-end by the long-range Air sac cover 11 of extremity, and by controller 30, according to patient's electrocardiogram (ECG) signal, controlled inflation and the venting starting point of each Air sac cover 11, make to reach with patient's electrocardiogram (ECG) signal and synchronize.
In principle, based on electrocardiogram, Air sac cover 11 is through regularly inflating in Syst starting point and lose heart for the starting point at relaxing period, during the injection section in this cycle, first inflation of calf bladder cover 11, then be lower thigh Air sac cover 11, and be finally upper thigh Air sac cover 11, when controller 30 is correctly synchronizeed with electrocardiogram, ECP system will play a role to lower the afterload that heart must resist pumping, and increase the preload of filling heart, increase by this cardiac output (left ventricle per minute or right ventricle are injected aorta or Pulmonic blood volume).
Similar external counterpulsation apparatus existing pneumatic supply 20 substantially by an air pressure side Pu 21 and a pressure-accumulating tank 22 of helping Pu 21 to be connected with air pressure, formed; As for, controller 30 is comprised of an intake valve 31 and a gas bleeder valve 32 of being located between pressure-accumulating tank 22 and Air sac cover 11, mainly sees through intake valve 31 and the mutual On/Off of gas bleeder valve 32 and reaches and make that Air sac cover 11 is inflated, disappointing object.
Yet, so structural design also cannot be adjusted the pressure keeping after Air sac cover 11 inflations according to demand, and the inflation of Air sac cover 11 and lose heart and controlled by intake valve 31 and the mutual On/Off of gas bleeder valve 32, cannot produce incremental pressurization or relaxation effect, not only easily cause patient uncomfortable, more make external counterpulsation apparatus cannot extensively be used in the sufferers such as severe aortic valve disease, serious controlling of blood pressure are not good, serious lower limb vein thrombus.
